Equipments Details
Description
The 2DCC Multi-Module Molecular Beam Epitaxy (MBE) system features in-situ cryogenic ARPES and STM. Samples can be transferred directly into the characterization tools, without exposing them to atmosphere, allowing the properties of pristine surfaces to be studied. This allows us to quickly characterize their inherent properties and rapidly develop and optimize new 2D materials and heterostructures.
Capabilities:
2” diameter substrates
Adaptor for smaller 1 cm2 substrates
Se cracker
6 pocket e-beam source for transition metals (Al, Mo, Nb, Ta, V, W)
Effusion cells for Bi, Cr, Fe, Sb, Te
Ellipsometry for real-time film growth monitoring
Base pressure of 1 x 10-10 Torr
In-vacuo cryogenic STM with 4 independent probe tips
In-vacuo cryogenic ARPES (energy resolution 1.8 meV at 2 eV pass energy
Monochromator with He 1 (21.2 eV) and He 2 (40.8 eV) excitations
Current Process Capabilities:
